1. Thermochromic Pigments: These change colour in response to temperature variations. They're significant for creating dynamic products that interact with the user's environment or body temperature. 
2. Photochromic Pigments: These pigments change colour when exposed to sunlight or UV light and revert to their original colour when the light source is removed. This feature is perfect for creating engaging visuals that change in different lighting conditions. 
3. Glow in the Dark Pigments: Also known as phosphorescent pigments, these absorb light and then glow in the dark for a period of time. They are used to add functionality and aesthetics to products used in low-light conditions. 
Each of these pigments offers a unique way to enhance the consumer experience, adding value and interaction to products.
